Specs:

Shuttle AK32A Motherboard
Kingston 256MB RAM
Maxtor 20GB HDD
Nvidia GeForce MX440
500W PSU
Amd Athlon CPU

It's a custom-built PC, and when I powered it on for the first time, all the fans came on, the HDD's spun, and it seemed to be recieving power. But, I get no POST beep(s), no display or keyboard. HELP!!! :'(

Short, focused diagnostic steps and explanations to supplement the replies already here (not repeating every tip you have read). The symptoms — fans and HDD spin but no POST beeps, no video and no keyboard — point to a failure very early in the boot sequence. The aim below is to narrow whether the fault is: motherboard/BIOS, CPU/socket, memory, or a case short, and to produce concrete evidence you can report back (POST codes, LEDs, voltages).

  1. Visual inspection first — with power removed: look for bulged or leaking capacitors, scorch marks, or any displaced standoffs that could short the PCB. Inspect the CPU socket area with a magnifier for bent pins (common on older AMD boards).
  2. Minimal bench test (clean, repeatable): unplug everything nonessential; place the board on a nonconductive surface; connect only PSU, CPU+cooler, one known-good RAM stick in the recommended slot, video card (or onboard video), and the front-panel power switch or a momentary short of the power pins. Leave drives, USB, front-panel connectors, and extras disconnected. Power on and note any LED activity or POST codes.
  3. Use tools that add facts: a simple POST/POST code card will show the last BIOS code (two hex digits) so you know where POST halts. A PSU tester or multimeter can confirm +5VSB and main rails before assuming PSU is OK. Clearing CMOS (remove battery or use jumper with power unplugged for 60+ seconds) is worth one attempt.
  4. Interpret results: if POST codes appear, consult the Shuttle manual for that code. If LEDs show CPU/DRAM/VGA failure lights, that narrows the faulty domain. If nothing at all (no LED, no POST card activity) after the bench test, the board—or occasionally the CPU—has likely failed.

Safety note: always unplug AC before moving components, keep ESD precautions, and keep the CPU heatsink mounted when you test. If you want, post the POST code or LED pattern and the exact behavior after the bench test and someone can help map the next step.

hi,how much custom,did you install the cpu onto the motherboard ,if so did you make sure it had coating of thermal past ,and was making a correct connection
also i would try connecting it all out side the case to make sure its not shorting out in the case some how

This sounds like my issues. It turns on starts up you see windows logo. Then the screen goes black. People say go into safe mode. I can't even do that. I will not allow me to much of anything. I never get to the start menu. If anyone could help me it would truly be appreciated. I only have one computer and I use that for my children homework and homeschool. Thanks guys.

are you sure you attached the PC speaker? Not your computer speakers where the sound comes out, but the tiny speaker that connects to the motherboard to beep when it finds problems. Also, make sure your video card is seated properly, and check the monitor cable to make sure it works properly.

Of course, this is all assuming you double checked to make sure the monitor was on!

double check if the ps/2 keyboard and mouse was inserted to their port.(not swapped)

no beeps, no display, no keyboard but the computer turns on..

1. remove your motherboard from the case
2. test your motherboard using a new or known to be working PSU
3. replace processor with a good one, your processor might be broken
4. when all else fail, motherboard is defective.

commented: tnx for the info +0
